JQuery :: Can't Access Object Variable From Object Method

Mar 10, 2011

I am trying some simple things with javascript and trying to use it in a object oriented way. However I am now facing a problem in which I can't access an object variable from an object method. I am using jQuery.

My code is as follows;

Code:

My problem is that the variable msg1 does not work when accessed from function called from the jQuery get function. I get the message undefined. Therefore I am wondering, is there a way how I can access msg1 of my object instance from the get function of jQuery?

Access A Server File Using A File Name Contained In A Variable

Jul 9, 2009

Im writing client-side javascript and I want to do a server side include. There are many server files but only one will be included. These files contain peoples names and phone numbers. This info is packaged as a line of javascript but I can change that packaging if necessary.

The file name to include is being passed as a url parameter: [url]

I know how to parse the url string and stuff the ID number into a javascript variable.

I set <ICODE> foo = "/people/12345.html" </ICODE> and tried <ICODE><!--#include virtual="${foo}" --> </ICODE>
but this did not work.

Is there a way to do this with javascript given that the name of the file I wish to include is contained in a variable? If not, what is the usual way of getting the data in the server file into my client-side javascript?

JQuery :: Cannot Get Access To Object

Feb 7, 2011

I have UL tag:

<ul id='ul'>
<li id='li1' class='someclass'>
li1</li>
<li id='li2' class='someclass'>

[Code]....

Now we have alerts only for three old elements. This is clear. Because these elementes have been initiated before page generated. But the new one is ignored.

The question is - how i can add new elements to the UL list? It would be glad if "jQuery.each" could read four and more elements - not just the first three initiated elements.

Need To Only Access Object On Demand

Jan 20, 2010

I have 95 different objects like this one:
obj1Object = {
name: "some name",
type: "type",
picid: "001",
maxvl: 500000,
minvl: 5000,
clsid: 1,
movable: true,
size: [45, 45],
note: "Some text here"
}
Now what I need is to access these objects only when I need then. Right now they all load when accessing my program so all 95 of them are "somewhere" in memory.

Access An Embed Object Via Javascript

Jul 23, 2005

I want to access the features of a plugin without actually embedding
it into a page. Is this possible? Eg

The code to embed the object into a page is:

<OBJECT classid='CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5
codebase='http://www.test.com/plug.cab#version=3,1' "id='myPlugin'
height=&#390;' width=&#390;'>

<EMBED type='application/x-myPlugin' name='myPlugin' hidden='true'
src='in.txt'></EMBED>

</OBJECT>

I could simply add this using document.write, but for various reasons
I dont want to do this.

I would rather do something like:

var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-Web-Plugin"]) ?
navigator.mimeTypes["application/x-Web-Plugin"].enabledPlugin : 0;

myObj = new object("CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5");

myObj.pluginMethod

How Do I Access The Object Instance From Within Class

Apr 22, 2007

I have a javascript object which dynamically generates a table adding, deleting and moving rows as the user clicks on buttons or links. Problem is when I generate a table row and add the javascript method call to my class, I have to put the object instance name variable of the class in order for it to be called from the onclick=function(). This is seriously limiting, but I'm stuck for a way round it. Heres a edited of the code so you get the idea....

Instantiating the object :-

var dtl = new DynamicTableList("table1", $
{myObject.allFieldsAsJavaScriptArray}, true, true, true);


My javascript class DynamicTableList, note the dtl javascript object
instance variable being referred to in the addRow function. How can I
avoid this???

function DynamicTableList(thisObjName, tableName, options, showDelete,
showUp, showDown)
{
this.processRow = function(r, row, up, down)
{
...
};

this.processRows = function()
{
...
};

this.getVisibility = function(visible)
{
...
};

this.delRow = function(button)
{
...
};

this.addRow = function(selection)
{
...

if (showDelete)
{
var cell2 = document.createElement('TD');
var inp2 = document.createElement('IMG');
/
************************************************** ***********************************************/
inp2.onclick=function(){dtl.delRow(this);} // Have to specify
dtc!!!!!!!!
/
************************************************** ***********************************************/
inp2.title='Delete'
inp2.alt='Delete'
inp2.src='images/delete.gif'
cell2.appendChild(inp2);
row.appendChild(cell2);
}

...

tbody.appendChild(row);

this.processRows();
};

this.moveRow = function(node, vector)
{
};
}

Obviously the code dtl.delRow(this); is being dynamically generated, but how do I replace the dtl instance name with something that'll work whatever the user of this class calls the instance of it!

JQuery :: Access To Parent Object Within Each()?

Oct 11, 2010

I've created an object with properties and methods. The object is associated with a form. The object iterates through the form and finds any inputs that are required. It then uses each to apply validation to each of the found inputs. From within each(), I need to access properties and methods of the parent object, but now this refers to the current collection object. How do I access the containing object?

JQuery :: How To Access True (This) Of Object

Jul 14, 2009

If "this" inside of a sortable "receive" function refers to the receiving object, How do I access the object to which the receive function belongs?

Example:
// Function that takes a JQ object and makes it sortable.
// We assign the "SortableRecieve" method to the receive event
MyObject.prototype.MakeSortable = function(JQOBJ){
JQOBJ.sortable({
receive: this.SortableRecieve
});}

MyObject.prototype.DoSomething = function(){
// Does something important
}
// The actual function that gets called when the receive event occurs
MyObject.prototype.SortableRecieve = function(event, ui){
// This function call won't work, because "this"
// doesn't point to the right thing!
this.DoSomething();
}
So how can I access the "True" this that refers to the object?

JQuery :: Traversing - How To Access Object

May 6, 2010

I have very simple question (ie probably simple for everyone with jQuery experience, but not for me). Lets say I have the following list

<div>
<li id="first"><a>one</a></li>
<li><a>two</a></li>
<li><a>three</a></li>
<li><a>four</a><li>
</div>

Now, if I want to get all the list items after the first, and change the text within the anchor tags, if a certain condition is met (eg change to capitals if it starts with a "t"). How can I do that? My approach was to get all the list items (after the first) with

Way To Access Object's Internal Properties

Apr 1, 2011

I am fairly familiar with the concept of Objects and their properties and methods, but javascript being object based as opposed to object oriented has me stumped on how to access an object's properties from an onclick event handler created for another object created within the original object.

In the example below, I have a constructor function called anyObj. to which I pass an object reference to an element.

anyObj has 3 properties and one function increaseWidth()

increaseWidth() creates a new button with an onclick event handler and this is where I have a problem.

The onclick function needs to increase the value of anyObj's this.width property. I originally had a line this.width += 10; in the onclick but quickly realised why this wasn't working because the this in the onclick function refers to the new button object and not the this.width property of anyObj.

The workaround I have used, and it works, is to make a copy of all the this.xxxxx properties. eg. width = this.width; and use the width variable in the onclick as you can see below. This "workaround" works fine but doesn't feel ideal to me.

So is there a better way to access the anyObj()'s properties from within the onclick function than the way I have done it? Obviously I would prefer to not have to make copies of all the anyObj() properties like I have to make them accessible to the onclick function.

function anyObj(divObj){
this.elem = divObj;
this.width = 50;
this.height = 50;

How To Check The Input File Object File Size On Client Side?

Dec 20, 2004

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:

1. Malicious user trying to collapse the website sending big files.

2. Users that have not seen the warning “Maximum size: 100 KB&#65533; for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.&#65533; And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!


I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:

“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:
